The platform at the top of my tower is sup- 10c 50 My tower consists of aoenter column G supported by two pieces of angle iron bent in the ported on suitable legs B at the bottom,prefcenter (see Fig. 9) so that the ends stand at right angles to each other. One limb of the angle iron projects down vertically and the other is horizontal on which the platform made in the usual form rests. In the middle the two pieces of iron are bent to fit the center column 0, something like a collar and the two are clamped to the column securely by bolts above the collar N. Collar N has only hooks 1; without a step. Through the verti- I0 cal limb of the angle irons D holes Z and 'r' are drilled to attach wires, two being drilled in each arm, one 0" at the end and one Z in toward the center. A short wirelextends from a collar J to the hole Z to stay the platform and I5 brace the tower. The collar J has four hooks above and four below to which are attached wires, those below running down to the corner supports of the tower. From near the outside of each corner iron A a wire runs to the hole Z of its corresponding arm of the platform support. From the outside of each corner iron A, two wires pass up and connect to the holes a" in the outer ends of the arms of the platform to each side of its corresponding corner to prevent the tower twisting from any cause.

The center column 0 projects above the platform and bears a cross piece I. From each end of this cross piece a column H pro- 0 jects and bears a cross piece I at the top. On the top of this cross piece I a hollow cylinder G in line with the center column 0 is placed. On top of this cylinder is a collar G which is held by brace rods a that pass down and con- 5 nect to the angle bars D and serve to stay the whole upper part of the tower. It will thus be seen that there is an open space just below cylinder G to afford an opportunity for securing a windmill to the top of the tower in the usual manner.

The center column 0 is made of gas pipe and is of course hollow. The opening thus left in the center of the tower affords a convenient place for the pump rod of a wind- 5 mill. The lower end of the column 0 rests in a socket C which is supported in the casting E to which the legs B are attached. The lower end of pipe 0 rests on a powerful coiled spring F which tends to support it. The spring F is to compensate for anyunequal expansion or contraction that may take place in the various parts of my tower, and to relieve any sudden strains due to gusts of wind or other causes.

The method of attaching the wires is not material to my invention. I prefer to use the bolts S at the bottom so that it will be easy to draw them together. It would be possible to construct a tower without the connecting 6: rodstbut it is better to use them. Three legsB might be used instead of four or a greater number than four might be used. A smaller central column 0 can be used if more sets of wires are used and attached to collars nearer together on the column and if a larger central column is used fewer sets of wires will be required, and if the column is very large only one set of wires will be needed.

The tower will stand and be effective without spring F at the bottom of the central column, but is better with it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A tower with a central column resting on suitable legs anchored at the corners, and sets of guy wires attached at short intervals to the central column and to the anchor plates at the corners, each set consisting of a wire for each leg, and all the wires of each set attaching to the column at the same height.

2. In a tower, the combination of the legs, B, with the central column, 0, the anchor irons, A, and the wires, 0, substantially as described.

3. In a tower, the anchor bolts, P, passing up into the anchored plates, in combination with the stay rods, 25, and the tower above, substantially as described.

4. In a tower havinga central column supported on four suitable legs, the central column being stayed by guys, the combination, with a square platform at the top, of diagonal guys as 2 passing from each corner of the platform to the anchor plates next adjoining to prevent twisting of the platform, substantially as described.

5. In a tower platform for a tower having a central column, the combination of the angle iron, D, bent to form a collar around the central column; the stay rods, a, passing to the top of the column andthe guys, Z, attached to the column below, substantially as described.

6. In a tower having a central column stayed by guys, the combination of a platform at the top with wires 2, attached to the platform running in lines at oblique angles to a plane passing through the central column and from opposite sides of the plane to prevent the tower from twisting.

7. In a tower, the combination, of a central support, E, having a socket to receive the legs and a socket for the vertical, central standard; the legs, B, fitted in the sockets anchor irons, A, with sockets to receive the lower ends of said legs; a central standard, 0, resting in its socket on the central support; a spring in said central socket under the standard to support the same; and guy wires, 0", in sets attached to the standards, 0, and anchor irons, A, substantially as described.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
